Thanks for the reply. Basically, that is great information, but doesn't really answer the question I asked. What I really want to understand is what is the maximum number of EP that a server has. Obviously, if I give 800 accounts the ability to use 100 EP each, then I expect that at some point, I would need X number of EP to support that. Assuming 20%, just for silliness, that is 16k EP. Am I over selling? Do I have 16K EP? Is there a way to find that out without one day finding out I don't?

That was the formula I was looking for. I was missing that it was based on Max Workers! So, the Apache default is 256 workers. That basically means that the max EP a default server could serve is 256 EP, provided it has the memory to do so.

So, this random guy in the internet says he is used these as his limits. These limits look amazing. Expect that he is giving, in theory, the user 25% of the server's resources with a 60 EP limit, except he isn't. He has limited the memory usage to 1024MB, that means that each process is really limited to 17mb.

I guess, I should comment on 100 total connection, in case someone is reading this. If his server is a mail server, and he has an office with 10 people reading mail... they will have major issues with a connection limit of 100. I have 6 emails I check right now and I'm using 17 connections on my account.
